. York," have invented'a new andlmproved Metallic vWindow Frame and Sash, of which the followingisa full, clear, and exact descrip-` tion...4

This linvention relates to' metallic Window sashes and frames, and has for its object; the

'pro'vision'of a thorouglily-reproof windowframe and .sashes coperating. therewitlr of durable and simple construction, in which the parts are so vdesigned and arranged thatl the WindoW-frameoccupies a minimum amount of spaceand is adapted for use under a great variety of conditions; l

With the object above stated and others of minor character'in view, as will appear when` j the invention'i'sfully disclosed, the same con-- `sists inthe novel contruction, combination,

and arrangement of parts hereinafter fully described and havingthe novel features thereof specifically pointed out in the appended claims; it being understood that various changes in thel exactform of the elements'of may7 be made-without-departing from the .3 i

the invention and of their mode of assemblage spiritthe-reof. Reference is to'be had to the accompanying drawings'forminga part of this specification, in which similar characters of reference indicate corresponding' parts in .all the views.

Fig-7 is a vertical sectionalxview through` A a portionof acar anda window having a single :Be4 it yknown that 1, PATRICK AUGUSTINE .TRAci, acitizen of the-United StatesQand a resident-of the city'of NewYork,'borough of Manhattan, in'v the county and State of New sash, which is 'arranged to open by upward movement. Fig. 8 1s atransverse sectional view upon theline of Fig. 7', the View be-v ing taken upon a much larger scale than Fig. i

7 and Fig-9 is a v ertical sectional View through a portion of a car and a car-'window having a single sash adapted to open by downward movement.

In a window constructed in accord with this vinvention the window-frame is madeup 'of a skeleton frameand a' casing supported there.- `by to conceal, the sash -weights and aord guideways for' the movement of said Weights. The skeleton frame consists, preferably, of vertical side members 11, a top cross-piece 2, and a bottom cross-piece 3, the side mem-- bers and the cross-pieces being'all arranged in the plane of the window, as best'seen in` Fig. 3. The casing carried by the skeleton frame includes side members i and top and 4bottommembers 5 and 6, respectively. The

side casing members 4 4 are secured upon the side members 1 l of the'skeleton frame, and

each of the members 4 4 projects outward and inward `from the side member. l of the skeleton frame upon which it is secured, forming from the side members,'as shown in Fig. 3.

The bottom member 6 of the window-frame casing covers the cross-piece 3 at the bottom of Athe skeleton frame upon its outer face and extends inwardvat both the top and bottom of the said cross-piece. The inward extension at the top of the'cross-piece 3 forms a sill 6 for the window-frame, and the inward extension slightly to hold the casing 'member l6 in association with the skeleton frame member 3.-

The side uprights l l of the skeleton frame of the windowproject forward to a considerat the bottom Ofathe cross-piece 3 is upturned able extent-and serve as the parting-beads 4which separate-the window-sashes. These partingbeads are each provided'with a channel-bar 7,'Which is rigidly secured in position, as s hownin Fig. l, projecting both inward outside of the rib formed along. the middle of dbg,

and outward from y the parting-bead and presenting at its margins rearwardly-disposed f anges which engage with coactinganges v tively. The shafts 8, upon which the pulleys are mounted, are so situated in the side mem? bers 1 1 of the skeleton-"frame that the pulleys 9 project forward from the casing mem- -bers 4 4 of the Window-frame to aconsider- Vable extent, suitable openings being provided in thecasing members 4 4 for that purpose.

The upper sash 12 and-the lower sash 13 of the window are somewhat similar in construction, each having its sides composed of anglebars 14 of peculiar cross-section, each of said bars 14 being provided at one margin with a ange 15 for engagement with one o-f the marginal lianges of one of the channel-bars 7, mounted upon the partingebeads of the window-frame, and beingprovided at its other margin with a ange 16 to afford a seat for the putty or other plastic material by'means of which the glass 17 is retained in the sash. Adjacent to its ange 15 each of the side members 14 of the window-sashes is spaced at a 'suflicient distance from the adjacent side member 4 of the window-frame casingto permit the free rotation of the corresponding pulley 9 without interference from the window-sash. The space provided in this way also permits' the extension of the chains 10 downward to the bottoms of the sashes,`

which arrangement 'the sashes are caused to move more readily within the window-frame. The bottom of the` upper sash l2 andthe top ofthe lower sash 13 are made up of 're- `verselyarranged angle-bars 18 and 19, which are of precisely similar cross-section, each be-I ingprovided at one margin with a ange to cooperate with the flange upon theother bar to form an air-tight joint when the window is I closed. The bottom of the upper sash is preferably strengthened, especially when the window is one of considerable'width, by a reinl forcing-bar 20, arranged beneath the bottom member 18 o f that sash. The top of the upper sash 12 is an angle-bar 21, which is somewhat narrowerthan the bottom member 18 to permit the sash to pass upward into the space the under surface of the top member of the window-frame casing.- The bottom of the .lower sash 18 is an angle-bar 22 of peculiar crossrseetion, Whichis provided at its outer margin with a downwardly-disposed curl Q3,

which 'engages with; the outer face of the window-sill to form` an air-tight joint therewith; thus serving-as a weather-strut.` The member 22 `is preferably reinforced by a bar 25 arranged beneath it, and a hook 24 or other l device of similar character is preferably-attached to the lower sash at the bottom to afford a handhold in raising the sash.

c y In the mullioned window illustrated iIhFig.

6 the structure is precisely the same as that r above described, except as regards the` mullion, which is designated as 30. The mullion is formed around the adjacent parting-beads of the two window-sections, and the casing of the mullion is formed by simply connecting two of -the casing members 4, so as toy form a single casing sufliciently large to receiveNand guide four sash-weights. The adjacent side members of the two window sections are spaced a slight distance apart, as shown, to permit free access to the weights inclosed in the casing of the mullion, andan opening 31 is formed in the casing of the mullion for the same purpose.

From the foregoing description and the drawings illustrative of the 'invention it will Vweights within the spaces afforded on both sides of each parting-bead.

As the window-sashes and all parts of the window frame are constructed wholly of metal, thestructure is perfectly lireproof and is also characterized by superior hygienic qualities, there being no erevices between wooden surfaces to facilitate the development of disease-germs therein. Comparatively few interstices are left in the window structure of the kind described 'in this application, and

IOO

these"inte`rstices being between metallic sur` faces or between surfaces of glass and metal any bacteria which may lodge therein do not multiply, but are soon destroyed, as it is well known that bacteria do not survive -for con' siderable periods upon glass or metal surfaces.

A special feature of the window construction which forms the present invention is found in the complete exclusion of air and moisture by the window when closed. It will be noted that the marginal anges of the sashes coact with the flanges of the channelbars on the parting-beads of the windowframe to form lapped joints, and in like manner the top and bottom members of the lower and'upper sashes, respectively,. lock to form a lapped' joint. The upper sash when raised to its fullest extent fits in a recess at the up- -per' part of the frame, asishown in Fig.

.'joint therewith o n account of the engagement ofthe 51rl23rat the outer margin of the bot 'tom member of .the sash withl the outer face v ofthe window-sill:

In the foregoing 'I paragraphs I have vde -scribed the invention as 'embodied in Windows .adapted primarily for buildings. and

" each having at least twosashes. It is obvious, however.rthat the invention may be em- Vbodied in windows having a single sash only fand lthat such windows may be used to advantage in raildwayvand tram cars. of these types are illustrated in 'and 9,-'both the upwardlyand downwardly Windows openingftypes being illustrated.

Referring to Figs. 7 and 8,140 40 designate thel side members ofthe frame for a window which opens by the upward movement of the sash. 41 designates the sill, which is secured upon the inner faces of the two sidemembers of the frame, and 42 designates the top or headpiece. At the inner edges of the two side pieces'40 I provide channel-bars 43, as in I -the forms ofwindows already described; but as a single sash only is provided in the window now to be described the channel-bars 43v areso fixed upon the-side members of theA `window-frame' that one'of the flanges of each channel liesin contact withthe'side member to which the channel-bar'is secu-red, .and the other lange 'only is spaced fromthe side 4member to serveasa guide and retainer' for 4the sash, which V1s designated 44. The sashl H44 is, 1nv general, very similar to the sashes already describedand is supported by chains l45,- connected with 'counterweights 46, the

chains being passed over pulleys 47, supported f upon shafts 48, mounted in the side members of the window-frame.

In the form of window shown in Figs; 7 and'- 8 the side members ofthe window-frameare extended-upward a` considerable distance abovey the normal position ofthe sash, so

that thev window may be raised by sliding the sash upward into the" space left for that purpose, and when raised the sash will be sustained in any position by means of the coun- A terweights 46.

` provided to `receive it.

In FigQQ a window is illustrated invvhich the-frame is composed of side members 50, a

sill 51,y and a top-piece 52. The side members 50. are `provided with channe/lfbars 53,

frame to permit the sash to have a'cert'ainy amount of play to and fro in the frame, and p Figs. 7, 8,'

with a ilange thesashis provided `at the bottom 56, which is-adapted to engage with the front or outer face of the sill of the frame. In ormust be raised slightly,

the sill .5l and the inward movement of the sash to permit it to pass downward into the pocket is made possible. When thesash is raised slightly and drawn inward from its normal position, it lies in a vertical plane and fmay be easily lowered into the pocket 55; but when the windowis closed the sash is'swung slightly forward or loutward at the bottom, causing it to occupy the oblique position shown in Fig. 3. In this orm'ot window the sashis supported by chains attached tojcounterweights and 'passing over the pulleys in precisely the same way as shown in Figs 7 and 8, Hence further descriptionk vthereof appears to be unnecessary.
